KE Y-FASTENER.

Specification of Letters Patent.

1 atented. April 27, 1909.

Application filed June 9, 1906. Serial No. 321,008.

To all whom it may concern:

Be it known that I, ELIZA ETH JANE, PEP- PER, a citizen of the UnitedStates, residing at Jackson, in the county of Cape Girardeau and Stateof Missouri, have invented new and useful Improvements in Key-Fasteners,of which the following is a specification.

This invention relates to an improvement in key fasteners designedprimarily to prevent unauthorized manipulation of the key from outsidethe door. a

The main object of the invention is the production of a fastening meansdesigned to be readily applied and cooperating with any ordinary form ofkey, the fastening means being readily capable of suchadjustment as willregulate the holding effect on the key to the extent desired. Y

The invention will first be described in the following specification,reference being had particularly to the accompanying drawings, in which:

The figure is a view in elevation, showing a portion of the doorcarrying the lock, my improved fastener being illustrated in appliedposition.

Referring particularly to the drawings, 1 represents a door to which issecured in any desired or preferred form a look 2. The lock is providedwith the usualkey opening 3 designed to receive and support any ordinaryform of key 4, by which the usual bolt is operated.

My improved fastener comprises an endless band 5 of spring material,preferably of the ordinary coil 's ring type so that the bagilld isuniversally exible, as Well as extens1 e.

In connection with the band, I utilize hook fasteners 6 and 7, arrangedin pairs above and below the lock. The respective pairs'of hooks, whichare referably, though not necessarily of the rig tangle type shown,aredisposed in alinement transverse the door above and belowthe lock, thehooks of each pair being. respectively spaced apart. a distanceconsiderably in excess of the diameter of the; ring 8 of the key and onopposite sides of the vertical plane of the key ole.

In use, the key having been turned'to locking'position, the fastener isengagedover the upper pair of hooks .6, and then passed throu h the keyring and into engagement with t e lower pair of hooks 7. This operationdisposes the band in the form of an oblong loop whose longitudinal sidestretches aredrawn inwardly by the ring of the key, toward which theyconverge downwardly and upwardly from the upper and lower set of hooks,whereby the said longitudinal side stretches are held under tension andexert opposite ressures on the ring of the key. As a resu t the key willbe held from rotary movement by the resistance of the stretches tofurther distention, any twisting action on said stretches produced by anattempt to turn the key increasing their resistance to the rotarymovement of the key.

It isto be understood that the band 5 is, when in applied position,under such tension as to efiectively' hold the key against movement,though it is obvious that if desired such tension may be increased bycoiling the band about the hooks 6 or 7 to decrease the normal length ofthe band between the hooks and thereby increase the tension. By preference, the lower pair of hooks 7 are disposed closer to the key thanthe u per pair of hooks, said hooks 7 being spaced apart a greaterdistance than the hooks 6. This construction provides for an increasedangular relation of the sides of, the band below the key so as tofurther increase the holding efiect at this point.

The fastener as a whole is readily applied or removed, and the hooks 6may be of the screw type so that the entire structure is renderedportable for application to any desired door.

resisting a turning movement of the key in the lock, said meanscomprising fastening elements secured to the door in pairs above andbelowthe lock,'the elements of each pair being spaced apart a distanceexceeding that of the maximum diameter of the key ring, and on oppositesides of the vertical lane of the key hole of the lock, and an en essextensible band adapted to engage the elements of each pair and to bepassed through the key ring, the ends of the band engaging the elementsbeing maintained by the elements on a plane below that of the key ring,and said elements being so disposed as to maintain the band underextreme tension. I0 In testimony whereof, I ailix my signature inpresence of two Witnesses.
